Use the Pythagorean Theorem to solve:

We are given the Hypotenuse (c) and one of the legs (b), so we can plug those values in to solve for a:

a² + (6.8)² = 8²

a² + 46.24 = 64

Subtract 46.24 from both sides:

a² = 17.76

Square root both sides:

a = √17.76

a ≈ 4.21 = x

Customers at a yogurt shop took a survey. The results showed that 162 customers rated the shop as being "very aatisfactory". The number represented 45 of the total numbee of customers who took the survey. What was the total number of customers who took the survey?

Answer: 360 people

Step-by-step explanation:

162 people who took the survey represented 45% of the total participants.

Assume the total participants is x.

The expression would be;

162 = 45% * x

x = 162/45%

x = 360 people

Jazmine can run 4 5/6 miles in 2/3 of an hour. How many miles can she run in 1 hour?

Answers

Step-by-step explanation:

Given : Distance run by Jasmine in [tex]\dfrac23[/tex] of an hour = [tex]4\dfrac56\text{ miles}=\dfrac{24+5}{6}\text{ miles}[/tex]

[tex]=\dfrac{29}{6}[/tex] miles

A funnel is shaped like a cone and is 4.5 inches high and has a diameter of 6 inches. What is the volume of the funnel? Use 3.14 for pi Round your answer to the nearest hundredth​

Answers

Answer:

Step-by-step explanation:

V = 1/3 pi r^2 h

r = d/2

r = 6/2 = 3

h = 4.5

V = 1/3 *3.14 * 3^2 * 4.5

V = 1/3 * 3.14 * 9 * 4.5

V = 1/3 * 127.17

V = 42.39

You spend c dollars for p identical pairs of pants. A friend claims that because c increases if you increase p and p increases if you increase c either c or p could be the independent variable. Is your friend right or wrong? Explain.

Answers

Answer:

Your friend is wrong.

Step-by-step explanation:

Since we have that you spend c dollars for p identical pairs of pants. We can represent this using:

C = kP.

Where k is the price for one pair of pants whereby the amount of dollars you spend depends on the number of pants picked.

C is the dependent variable here, depending on P and P is independent. Therefore, you have only one independent variable which is P.

A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour. If Brian keeps his pace, how long will it take him to run a half marathon?

Answers

Answer:

2.053 hours

Step-by-step explanation:

From the question,

A half marathon is around 13 miles. Brian can run about 6 1⁄3 miles per hour.

If Brian keeps his pace, how long will it take him to run a half marathon?

This is calculated as:

6 1/3 miles = 1 hour

13 miles = x hour

Cross Multiply

6 1/3 miles × x hour = 13 miles × 1 hour

x hour = 13 miles × 1 hour/6 1/3 miles

x hour = 13 ÷ 6 1/3 miles

x hour = 13 ÷ 19/3

x hour = 13 × 3/19

x hour = 39/19

x hour = 2.0526315789 hours

Approximately = 2.053 hours

It will take him 2.053 hours to run a half marathon.

what is the linear equation for this graph? (y=mx+b)

Answers

Answer:

y = -3x - 3

Step-by-step explanation:

the y-intercept is -3 as shown in the graph, so, b = -3

if you count, the rise is 3 and the run is -1, so the slope will be -3/1

-3/1 equals to -3

y = -3x - 3

Answer:

y = –3x – 3

Step-by-step explanation:

m = the slope which is 3/1, or 3. Since the line is going from the bottom right corner to the top left, it is a negative slope so –3.

b = the y-intercept which is –3.

So,

y = –3x – 3
